136 ANALYSIS OF THE FOUR PRINCIPLES (CONTINUED). 
different influences through which it arises; while indiscriminate 
survival and its equivalent, indiscriminate elimination, seem to be 
sufficient for the designation of a process which, as compared with 
selection, is rarely effective in producing the transformation of races. 
4. Table of the discriminate and indiscriminate jorms of the four segregative 
principles. 

Ture EIGHT ForRMS. 
THE RESULTS. 

PARTITION. 
. Discriminate partition = segregate asso- 
ciation, 
. Indiscriminate partition with more or less 
loss of power to perpetuate the original 
habitudes unchanged. 
SUCCESS. 
. Discriminate success = election. 
. Indiscriminate success = indiscriminate 
failure. 
ISOLATION. 
_ Discriminate isolation = segregate inter- 
generation. 
. Indiscriminate isolation with more or less 
loss of power to reproduce the complete 
average of the innate characters ot the orig- 
inal stock. 
SURVIVAL. 
. Discriminate survival = selection. 
. Indiscriminate survival = indiscriminate 
elimination. 
 ————— 

. Grouping of individuals according to habi- 
tudes and acquired characters, and so 
producing habitudinal segregation, and 
giving an initial tendency toward segre- 
gate breeding. 
. More or less divergence in the habitudes 
and acquired characters of the separated 
groups, especially when the groups are 
very small, and so producing initial habi- 
tudinal segregation. 
. Success and influence of individuals accord- 
ing to their acquired fitness for the condi- 
tions, both social and physical, in which 
they are placed, producing intensified 
habitudinal segregation. 
. When the number of individuals that es- 
cape from a sweeping catastrophe is very 
small, they will be unable to perpetuate 
the original social organization unchanged. 
. Grouping of individuals according to their 
aptitudes and innate characters, and so 
directly introducing segregate breeding 
with divergence of characters, 7. e., racial 
segregation. 
. More or less divergence in the aptitudes 
and innate characters of the isolated 
groups, especially when at the time of the 
first setting apart the group is represented 
by but one, or but few, individuals, and 
so producing initial racial segregation. 
. The efficiency of individuals in living and 
propagating will vary (and so their survi- 
val will vary) according to their innate 
fitness for the struggle of life, and thus 
the fitness of the race will be increased. 
. When those indiscriminately surviving are 
very few, it will be impossible for them to 
reproduce all the innate characters of the 
original stock unchanged.
